Calling richTextBox from other namespaces many times

In namespace WindowsApplication1 I declare the richTextBox1 which I want to CALL FROM OTHER NAMESPACES MANY TIMES MAKING CHANGES that I want TO STAY. How I could make it for maximum performance ?

The first time I declared it as public static removing the keyword this in front of it.
But every time I was going to the Form1.cs[Design]* and I was making just a little change to the richTextBox1 the static was leaving and the this was appearing again.(Can I stop it happens?)

The second time I was passing the richTextBox1 as reference variable for many functions. But I think it is slow.(Is it realy slow?)

Your 'static' change is happening because the Windows Forms designer requires the controls on the form you're designing to be instance variables.

If you want, yes you can pass the rich text box into the functions you want to use it in. No, this is not slow, you're not copying the rich text box, just a small pointer to the rich text box.

A better solution is NOT to use static, and instead pass the rich text box once to the other class, then store that variable in the other class. For instance

class Form1
{
   ...
   // make an instance of the other class
   MyOtherClass theOtherOne = new MyOtherClass(this.richTextBox1);
}

class MyOtherClass
{
   private RichTextBox theRichTextBox = null;
   public MyOtherClass(RichTextBox rtb)
   {
      theRichTextBox = rtb;
   }

   void DoSomething()
   {
      theRichTextBox.Text = "hey I've modified it from another class";
   }
}

#include "witty_sig.h"

The simplest way is to add a Button to your container (like a Form or UserControl) and a ContextMenu that is either defined with the MenuItems you want, or adds them dynamically in the ContextMenu.Popup event handler. In the handler for the Button.Click event (inheritted from Control), call ContextMenu.Show, passing the Button that was clicked and some Point, like the X and Y coordinates of the mouse position (remembering to transform the coordinates into client coordinates using Control.PointToClient) or some corner of the Button (like new Point(0, 0) for the upper-left corner, since the coordinates are relative to the control you pass in the first parameter).

Direct X Picturebox

Hi,

I just starting to play around with managed Direct X. What I want to do is create an application which has a windows form with a PictureBox containing Direct3D graphics but I'm having trouble getting started. I tried setting passing the PictureBox control to the constructor for Device and then simply blanking it to a uniform blue (borrowing code from tutorial 1 in the SDK documentation). I was calling the Render() method to do the rendering on the OnPaint event but nothing seems to be happening - the picture box remains defiantly grey!. What am I missing here?
What I'd ideally like to do is create a custom Direct3DPictureBox control inheriting from PictureBox so I can drop it into my apps without worrying about them too much.

Thanks

Subscript button for richtextbox?

BrownJacket18-Jul-04 3:28

18-Jul-04 3:28

I need to put toolbar item to my windows application to make the selected text subscript or when it pressed , typed letters or numbers will be subscript.

I searched more about this topic on the net but I can only find some this:

myRichTextBox.ToolbarLayout = "bold,superscript,subscript";

but doesnt work there is no option in the Richtextbox class like "ToolbarLayout"...

any help..I would be glad...thanks

Unfortunately, MS didn't expose all the functions of the RichText control for .NET.
You can do something like richTextBox1.SelectionBold = true but there's no such thing as richTextBox1.SelectionSubScript = true Frown | :(

But since the .NET RichTextBox in fact just wraps the Win32 RichEdit control you can use the structs and messages for this control to achieve subscript, superscript, various underline styles and so on.

Take a look at this article here, I've added something similar to the RichTextBoxEx class already (look towards the end of the article).

This can be easily modified to add subscript/superscript formatting for a selected range od text.

mav

first of all , thanks mav , this is the second time you saved my life Smile | :)

I've read the article...I know I ll take a look at this article in the future a lot...it will help me the modify RTB's class properties...

I found something like that after I've read the article you prefered.

richTextBox1.SelectedText = "10";
// Set the CharOffset to display superscript text.
richTextBox1.SelectionCharOffset = 10;
// Set the superscripted text.
richTextBox1.SelectedText = "2";
// Reset the CharOffset to display text at the baseline.
richTextBox1.SelectionCharOffset = 0;

This is the article

And another article I've found , it's here

I'll check them and try , if they doesnt work...I 'll try modifying the class. OMG | :OMG:

Thanks for your help again... Smile | :)

Creating object using ActiveX Component

Member 32469018-Jul-04 3:10

Member 324690

18-Jul-04 3:10

I've downloaded an ActiveX component and attempted to create an object of a type contained in the component. However, in using the following line of code

/cm11a.controlcmClass x10 = new cm11a.controlcmClass();

I receive the error:

'cm11a.controlcmClass.controlcmClass()' is inaccessible due to its protection level

The class is declared as public and no alternative constructors are available.

I've also tried:

<br />
      Type type=Type.GetType("cm11a.controlcmClass",false,true);<br />
      object x10= Activator.CreateInstance(type);<br />
      ((cm11a.controlcmClass)(x10)).Init();<br />

but get an exception on the 2nd line as type is null (ie the "GetType" call failed).

Any ideas or suggestions on getting either method to work would be greatly appreciated.

Thanks
Ashley

PS If anyone knows of a library which can be used to control a CM12 interface I'd love to hear of it

What does this mean?

Do you mean to ask how to use one of the following classes: System.Collections.DictionaryBase, System.Collections.Specialized.ListDictionary, System.Collections.SpecializedHybridDictionary or System.Collections.Specialized.StringDictionary.

Or do you mean to ask how to implement a natural language dictionary, like the Oxford English Dictionary?

{
SHFILEINFO ssfi, lsfi;
HIMAGELIST hSystemSmallImageList = (HIMAGELIST)
::SHGetFileInfo((LPCTSTR)_T("C:\\"), 0, &ssfi,sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
pSmallList->Attach(hSystemSmallImageList);

HIMAGELIST hSystemLargeImageList = (HIMAGELIST)::SHGetFileInfo((LPCTSTR)_T("C:\\"), 0,&lsfi,sizeof(SHFILEINFO), SHGFI_SYSICONINDEX | SHGFI_ICON);
pLargeList->Attach(hSystemLargeImageList);
}

Integrating the Media Player

Yonaz17-Jul-04 13:43

17-Jul-04 13:43

Hi everyone

i am trying to code a program that should be able to play videos besides other features.
I thought it would be easiest to accomplish the task by just integrating the Windows Media Player-COM-Object, but i couldn't get the controls to disappear (i want my own user-interface..). I read about mediaplayer-integration in a book called 'Advanced C# Programming' by Paul Kimmel. But he seemed to use a different com-object and the demo-app to that chapter doesn't compile (can't find the reference to AxMediaPlayer). The only COM-object i found, that looks like it has really something to do with the mediaplayer is this: AxWMPLib.AxWindowsMediaPlayer. But with this one i get these nasty mediaplayer-controls that i can't get rid of.

Can anybody help me with this, or does somebody know a better solution?

thanks in advance

i just downloaded the media player 9 SDK and tried to compile the c#-sample (named tune-clipper). As written i registered the wmppia.dll with regasm.exe and installed it with gacutil.exe (Global Assembly Cache Utility). This seemed to be successful. But as i tried to compile the tuneclipper i stumbled accross compile-errors (actually 18 of the same kind):
D:\dev\SDKs\WMSDK\WMPSDK9\samples\dotNet\csharp\Form1.cs(689): 'AxMicrosoft.MediaPlayer.Interop.AxWindowsMediaPlayer' does not contain a definition for 'controls'

I get this one when a call to Player.controls.xxx is made. Player is defined as 'private AxMicrosoft.MediaPlayer.Interop.AxWindowsMediaPlayer'. Player.controls seems to be undefined.. very strange.. (i guess Microsoft-code is supposed to run..)

Does anybody know a way out?

I'm not sure but I think the you may use the property 'uiMode'. Valid values are "none", "mini", and "full"... eg...

wmp1.uiMode = "none";

Also.. If you don't want the context menu for the Windows Media Control , use

wmp1.enableContextMenu = false; // true to turn it back on

Hope that helps..

Yup, thanks.

does your mediaplayer have the 'controls'-property?
As i wrote, mine somehow doesn't. Without it i can't really control media-files. All the play-, stop- and pause-methods are in there.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
